That's fake.

EvilHomer - 2016-02-18

How can you tell? I don't see any pixels.

Cena_mark - 2016-02-18

The sound and sequencing was likely from another drum machine or FL Studio.

EvilHomer - 2016-02-18

But... but you can see the lights light up! And he's clearly pressing buttons on it. Explain that, Doubting Thomas.

Old_Zircon - 2016-02-18

This isn't a sequencer, Cena, it's two Yamaha YMF262 chips (i.e. the synth sections of two AdLib soundcards)with a custom designed interface for low level control of the synthesis, people have been making them for about a decade.

Usually people have much more practical interfaces but this guy has fallen into some kind of wormhole.


A roommate of mine did something similar with the Commodore SID version of the Midibox platform a few years back, with every programmable parameter of the SID given a hardware control.

But yeah, the sequencing was done elsewhere.

Old_Zircon - 2016-02-18

Actually, looking at the description there was no sequencing, he's doing what I assumed when I submitted the video - playing a MIDI file he downloaded and tweaking the FM parameters occasionally.

This was posted primarily for the ridiculous control scheme that's pretty much not being used.

yeah its mostly dark up north there

Old_Zircon - 2016-02-18

This SID one from the related videos is a similar design to my old roommate's build:

I'm waiting for a new 1mm cutter and some heavier aluminum so I can go down to the local community machine shop and CNC the front panel for mine, then I just need to get some screens and about 2/3 of the components and I'll be ready to start soldering.

Going for the standard Wilba panel for now, might add a 64x64 button matrix as a separate rackmount module later.


Old_Zircon - 2016-02-18

16x16 I mean.

There was a time when I was looking into building the SID chip Midibox. I decided against it since all the SID chips owned by me were in working C64's at that time, and I figured that is where they should stay. I've heard tell that taking the SID chips out of their natural environment can have a negative impact on their sound. The guy who told me that seems to know more about c64 related stuff than anyone I know, so I took his word for it.

Hey, OZ. I recently built a panel for a project of mine (Doepfer DIY synth) using a program called Front Panel Express, the software was easy to use, and I think I ended up paying to have them make it for me. I went this route mainly because I wanted to add slots for sliders, and knew I'd fuck it up if I did it myself.

Cena_mark - 2016-02-19

I'm sorry. I know it's not fake. I was just mad at you for saying "Man's Dick Caught by Train Doors" was staged.

Old_Zircon - 2016-02-19

The Front Panel Express quote for the Midibox Seq panel was 0, unfortunately. 4 hours on the CNC is , plus another or so for aluminum, cutters and cutting fluid.

Laser cut acrylic is cheaper to have someone else do but aluminum milling is generally cheaper to do myself.

Which is too bad, because I'm not one of those people who likes using the CNC, it's about as fun as vacuuming my apartment.

Old_Zircon - 2016-02-19

I can't really say one way or the other about SID sound because I've only ever used them in a c64. I'm sure they'd be less noisy, anyway, since the noise is almost all bad shielding and not enough isolation from the RF modulator, from what I've read.

Have you tried shorting the audio input on the c64 a/v DIN jack to ground when you're not using it? I finally did it last year and it helps a lot!

My main issue with using SIDs in c64's is that it's so easy to damage them. I lost the 6581r4 (the rare one!) in my commodore by accidentally plugging the audio output into the video in on a stock Commodore monitor and I've been kind of touchy about using it in unfamiliar setups ever since. Tried running it through an isolation transformer but it changes the sound a lot. I've heard all the horror stories about voltage spikes in mixers frying them and stuff like that but I thought they were exaggerated. They aren't.

Old_Zircon - 2016-02-19

Cena, I totally missed the joke, but thanks for the excuse to ivejournal about music equipment.

Scrimmjob - 2016-02-19

I didn't realize that there was an audio input on the DIN jack, I'll have to check into that. The C64 can be pretty touchy, I ruined one of my C64-C's by using an AV DIN cable from a Sega Master System that was sold to me as a C64 cable on Ebay. It still worked afterwards, but it would only display in black and white.

The more I think about it I'm pretty sure I spent closer to 0 on that control panel. It was worth the convenience though!

memedumpster - 2016-02-18

Is this from Space Cop?

EvilHomer - 2016-02-19

You are the only person who remembers that exists.

EvilHomer - 2016-02-19

Or rather, were, given that I and anyone else who reads your comment will now remember it, too.

memedumpster - 2016-02-19

Not true, they can't keep it in stock actually. Space Cop is vastly superior to NES music, incidentally.



EvilHomer - 2016-02-19

Sorry, I already forgot what we were talking about.

Something about clopping?
